Syrian civil war: The Battle of Ras al-Ayn ends with the expulsion of Islamist forces from the city by the People's Protection Units (YPG).

The Syrian civil war began with the Syrian revolution in March 2011, when popular discontent with the Ba'athist regime ruled by Bashar al-Assad triggered large-scale protests and pro-democracy rallies across Syria, as part of the wider Arab Spring. The Assad regime responded to the protests with lethal force, sparking a civil war. The Syrian revolution lasted almost 14 years and culminated in the fall of the Assad regime in December 2024. Many sources regard this as the end of the civil war.

The Battle of Ras al-Ayn was a series of armed clashes for control of the town of Ras al-Ayn during the Syrian Civil War, mainly between the Kurdish-majority People's Protection Units (YPG) and an alliance of Syrian rebel groups, with the occasional involvement of the Syrian Armed Forces. As result of the battle's first phase, the Syrian Army was expelled from the city by Syrian rebels, whereupon the latter attacked the YPG-affiliated fighters in Ras al-Ayn. In the following months, the city was effectively divided into rebel-held and YPG-held areas, with intermittent fighting resulting in the gradual expansion of the YPG's territory in the city and its surroundings. Islamist and jihadist factions soon became dominant among the rebels in the region, further contributing to tensions with the secular-leftist YPG. In July 2013, the battle's final phase erupted and ended when an alliance of YPG-led troops completely expelled the rebels from Ras al-Ayn.

The People's Defense Units (YPG), also called People's Protection Units, is a libertarian socialist US-backed Kurdish militant group in Syria and the primary component of the Syrian Democratic Forces (SDF).
